POWER PERFORATING-MACHINE.

Specification of Letters Patent.

Patented April 21, 1908.

Application filed July 23, 1906. Serial No. 327,416.

To all whom 'it may concern:

Be it known that I, VALLACE G. CAPI- TAINE, a citizen of the United States, residing at Richmond, in the county of Henrico and State of Virginia, have invented certain new and useful Improvements in Power Perforating-Machines, of which the following is a specification.

This invention relates to perforators or punches for paper or other sheet material, and one of the principal objects of the same is to provide means for gearing up a machine of this character so that it may be run by power, punches are timed by the gearing to remain in position to permit the sheet material to be fed into the machine and to then operate quickly to punch the sheet and retract the 5 perforators to give time for feeding another sheet into the machine.

Another object is to provide simple and efficient means for operating a paper perforator at suitable intervals to'permit sufficient time between each operation to properly feed the paper to the machine.

IIn the use of hand operated perforating machines it has been found difficult to turn out perfect work, and even then the operation is slow and tedious.

One of the principal objects of my invention is to overcome the defects existing in such machines.

The objects referred to are accomplished by means of the mechanism illustrated in the accompanying drawings, in which- Figure l is a front elevation of a machine made in accordance with my invention; Fig. 2 is a side elevation of the same; Fig. 3 is a vertical front to rear section; Fig. 4 is a side elevation, taken from the side opposite to that shown in Fig. 3 3 Fig. 5 is a plan view of the machine; Fig. 6 is a side view of a pinion and sliding shoe 3 view of the eccentric shaft, and Fig. S is a similar view of the cam bearing for said ec centric.

Like numerals designate like parts wherever they occur in the different views of the drawings.

Referring to the drawmgs for a more particular description of the machine, the numeral 1 designates the base of the machine, and 2, 3, are the frame bars which are suitably tapv ed to provide bearings for the shafts 4, 5, an

and in which the perforating tools or Fig. 7 is a side and end 1 6. The female die plate 7 and the l movable male die S, may be of any required conformation, depending upon the character of the 'work to be done and the class of material to bev operated upon. The shaft 4 is provided with an eccentric ll, which engages a cam bearing 1lb connected to the male die member, and by means of which the male die S is moved up and down relatively to the female die late 7. On the shaft h/l is a pinion 9, upon t ic hub of which a sliding shoe l() is formed or properly secured. Fixed to the shaft 5 is the large gear wheel, ll. This gear wheel is provided with cogs 12 which extend entirely around the periphery of said wheel, and a suitable number of said teeth or cogs l2 are extended laterally and inwardly as shown at 13, see Figs. l and 5, thus 'forming a smooth peripheral portion "Ill, between the lateral termination of the teeth l2 and 13, which smooth portion 14 only partially surrounds the wheel, while the entire peripheral portion of the wheel is smooth at l5, as clearly shown in Fig. 5. The pinion 9 engages the teeth 13, and the sliding shoe l() 'des upon the smooth periphery 15 thereby l l l i l sh serving as a guide to insure proper register of the cogs on the gear wheel ll and the pinion 9. On the shaft 6 is a fast pulley 1G and a f loose pulley 17, and a belt 18 from any suitl able motor engages the pulleys and may be l shifted by the lever 19 from one pulley to the other, as will be understood. Fixed to the l shaft 6 is a pinion 20 which is in mesh with l the teeth or cogs 12 of the large gear wheel. From the foregoing it will be obvious that the eccentric shaft 4L and the eccentric 4a are intermittently rotated, said rotation occurring at the time the teeth of the pinion 9 engage the cogs or teeth 13 of the large gear wheel. The male die S is carried down to l perfor-ate the paper and returns to its upper l, position during the time of engagement of l the pinion 9 with the cogs 13, while the said l die is held on its upper position during the rel mainder of the rotation of said large gear \wheel 11, the shoe l0 then sliding on the l l l smooth peripheral portion l5, of said gear wheel 1 l, to insure proper alinement and register of the cogs on the 'pinion 9 and the teeth 13, at the beginning of their next engagement. From the foregoing it will be obvious that l owing to the comparatively quick downward f and upward movement of the male die conl siderable time is given for the removal of the perforated sheets, and the feeding of the sheets to be perforated, and this during the continuous rotative movement of the large gear Wheel.

Various changes may be made in the arrangement and construction of the various parts Without departing from the spirit and scope of the invention.

Having thus described my invention, what I desire to secure by Letters Patent and l claim is i l. In a machine for perforating sheet mal terial, the combination With a female punch I member, and a male punch member, of means for intermittently reciprocating said i male member, comprising a gear Wheel provided With teeth extending around its periphery, teeth extending only partially around its periphery, and a smooth peripheral portion, a gear pinion meshing with the peripheral teeth of said gear vlieel, a second pinion adapted to enOage the gear teeth exi tending partially around said Wheel, and cam mechanism carried by the shaft of said second pinion.

2. In a machine for perforating sheet material, the combination with punch members, of means for intermittently reciprocating one of said members, comprising a gear Wheel having peripheral teeth, a portion of which are extended laterally, and a smooth periph- I eral surface, a pinion meshing with said peripheral teeth, a second pinion adapted to engage said extended teeth, cam mechanism carried by the shaft of said second pinion, l and means also carried by said shaft for hold- I ing the reciprocating punch member away l from the other member.

3. In a machine for perforating sheet ma- I terial, the combination with punch members, of means for intermittently reciprocating one of said members, comprising a gear Wheel having peripheral teeth, a portion of which l are extended laterally, and a smooth eripheral surface, a pinion meshing Wit said peripheral teeth, a second pinion adapted to engage said extended teeth, cam mechanism carried by the shaft of said second pinion, and means also carried by said sh aft for holding the reciprocating punch member away from the other member consisting of a shoe adapted to bear upon the smooth peripheral portion of said gear Wheel.

4. In a machine for perforating sheet material, the combination with tWopunch members, of a continuously revoluble shaft, and means for intermittently reciprocating one of said punch members, comprising a gear Wheel having peripheral teeth, a portion of Which are laterally extended, and a smooth peripheral surface, a pinion adapted to engage said extended teeth, a sliding shoe mounted upon the shaft of said pinion and adapted to bear upon said smooth peripheral surface, a cam upon said pinion shaft, and a bearing for said cam, said bearing being connected to the reciprocating punch member.

5. In a machine forv perforating sheet material, the combination With a driving shaft, and a pinion mounted thereon, of a gear Wheel having peripheral teeth, a portion of which are laterally extended, and a smooth peripheral surface, a second pinion adapted to engage said extended teeth, a sliding shoe carried by the shaft of said second pinion, and adapted to bear upon -said smooth peripheral surface, a cam upon the shaft of said second pinion, punch members one of which is adapted to be reciprocated intermittently, and a cam-bearing secured to said reciprocating punch member.
